.SH SYNOPSIS
.IP
.nf
\f[C]
int mlx5dv_modify_qp_sched_elem(struct ibv_qp *qp,
                struct mlx5dv_sched_leaf *requestor,
                struct mlx5dv_sched_leaf *responder);

.SH DESCRIPTION
.PP
The QP scheduling element (SE) allows the association of a QP to a SE
tree.
The SE is described in \f[I]mlx5dv_sched_node_create(3)\f[R] man page.
.PP
By default, all QPs are not associated to SE.
The default setting is ensuring fair bandwidth allocation with no
maximum bandwidth limiting.
.PP
A QP can be associate to a requestor and/or a responder SE following the
IB spec definition.
.SH RETURN VALUE
.PP
upon success 0 is returned or the value of errno on a failure.
